Question

round 2: estimate each product to find the correct expression. which expression is closer to 300? $5 \times 63$ which expression is closer to 600? $27 \times 19$ which expression is closer to 4,000? $23 \times 41$ $21 \times 202$

Explanation:

Step1: Calculate $5 \times 63$

$5 \times 63 = 315$

Step2: Find difference from 300

$|315 - 300| = 15$

Step3: Calculate $27 \times 19$

$27 \times 19 = 513$

Step4: Find difference from 600

$|513 - 600| = 87$

Step5: Calculate $23 \times 41$

$23 \times 41 = 943$

Step6: Find difference from 4000

$|943 - 4000| = 3057$

Step7: Calculate $21 \times 202$

$21 \times 202 = 4242$

Step8: Find difference from 4000

$|4242 - 4000| = 242$

Answer:

1. $5 \times 63$ is closer to 300.
2. $27 \times 19$ is closer to 600.
3. $21 \times 202$ is closer to 4,000.
